Not so good enough report.
Me: I see. Another question can?
O: (They laughed) Yes, what is it?
Me: Why you made 24lbs tension for Nanoray 900? As for consumer, such 24lbs is not enough even for recreational players.
O: We make the racquet tension warranty based on racquets playing style. If the racquets is for control and speed, we decided to put 19-24lbs only because it’s fit to recreational player. For power such as Voltric Z Force 2 which is 28, we warranted at that because it’s for pro players.
Me: I would like to suggest that please increase the tension higher. I am Yonex fan, used Yonex since 6 years old. I would like to see Yonex is in 30lbs.
O: hurm.. we will discuss it in next meeting. Thanks for your suggestions.
I currently have the dilemma of whether to string my ZF2 past 28lbs or not. Conversely, my Voltric DG 10, which runs an almost identical design to the ZF2 (down to the compact quad frame head shape, tungesten grommet bumper strips at 8,10, 2 and 4 o'clock, etc). has been strung at 34 lbs, then 32lbs, no issues so far.
Super late to this thread but here's my take. Please let me know if I'm correct.
The tension of the strings will impact the "sweet spot" of your racket. So lower tension such as 23, 24 pounds will have a high "sweet spot." Higher sweet spot will decrease accuracy of the hit. However, high tensions such as 31+ pounds will have a smaller sweet spot. Higher tension is geared towards professional players because their accuracy is spot on. But what I don't understand is why I feel more repulsion at a lower tension than at a higher tension at times when I smash. I'd say I'm a intermediate player and I sometimes feel I get more power out of a 24 pound strung racket compared to a 28 pound strung racket. Can someone clear up the confusion and elaborate please?

String bed is more bouncy at lower tension so greater repulsion power can be generated. Bouncy string bed means accuracy is bad, so pro players trade off power to accuracy by going higher tension. In a real competitive game, your opponent does not give up open smash opportunity most of the time, you have to create opportunity to smash with accurate drop shots and net play. I hope I have cleared your doubt.
it doesn't make sense to have more repulsion power with higher tension, there is the general thought coming from newbies. Think of it like a trampoline effect; lower tension of string allows the string to stretch deeper and absorbs more incoming force and repels it back, shuttle stays at the spring bed longer but the repulsion power is bigger. The opposite happens to high tension spring bed.
Are you doing an apple to apple comparison in both scenario as string age, string type, incoming shuttle speed, racket type and etc all affect the results.
There were heaps of discussion in BC before,

that doesn't explain your theory of higher tension generates more power.The trampoline effect is really only needed for players still learning how to play. Most higher level players require more repulsiveness and feel from the string which means the racquet responds faster to small/ compact movements.
Comparison is very much apples to apples, same racquets and same reel of string.![]()

Power and control increase up to a certain tension
Go through all the threads on the links I provided and you will learn more about tension and power. Generally, lower tension generates more power with lesser accuracy and vice versa. Nanoray is a flexible + headlight racket and N90III is the opposite, stiff + head heavy. by looking at the spec, 10 out of 10 will take N90 III as the more powerful smashing racket, again, generally, stiff and head heavy rackets generate more powerful smash. My explaination is your strength and technique is developed to play better with flexible racket, so your swing and muscle memory is still staying with the flexible racket so naturally the power you can generate is lower. So it could be the combination of both.Here's the thing: My first racket is Yonex Nanoray 10 with default factory string (I'm guessing default factory string is probably like 18-19 pounds.) I tried out of my friend's racket, his Li-Ning N90III strung at 25 pounds. The string on the Li-Ning are significantly tighter than the Nanoray 10. However, I found my smash speed is faster with my Nanoray 10 strung at lower tension than the Li-Ning. It's hard to explain, but you guys know the feeling when you hit a good smash, like the sound the birdy makes when it flies. I just feel better with the lower tension. I saw the debate above and I'm not sure who is correct.

Dave010, You can disagree with my opinion, but saying I am wrong with evidence coming from your own tapping test just sound silly and arrogant.
Good post.
Same applies to shaft stiffness.
